(FS) ranges from 0.36 to 6,000 psig, 7.5 to 6015 psia. Each transducer module is congured with its own
calibration parameters on board and have 0.01% IS-50 or optional 0.008% IS-33 accuracy.
The three transducers, in combination with the internal control valve regulator, provide a dynamic output.
The operator can choose to control pressure either using a single, selected transducer or auto-range
control across all three transducers. The ratio between the highest FS range and the lowest FS range
within the CPC8000 cannot exceed 10:1. The three ranges can be chosen to optimise accuracy levels
across the full pressure span of the instrument.
In addition to the capacity for three active ranges, a fourth, barometric transducer is available as an
option. With this option installed a CPC8000, with absolute or gauge pressure transducers, can emulate
pressure of the opposite type.
3.1.1 IntelliScale Transducer Choices
The CPC8000 can be supplied with standard 0.01% IS-50 Transducers or optional 0.008% IS-33 trans-
ducers to give a percent of reading accuracy down to 50% or 33% of full scale respectively. Refer to Sec-
tion 4, Specications, for a full description of the accuracy specication and Section 4.7, IntelliScale.

Test / Calibration Parameters
Figure 3.2.4.1 - Main Screen Features
3.2.4.2 Screen Navigation
Individual screens are accessed by a series of touches on tabs, buttons or icons, which open screens
within the hierarchy of the instrument. Nomenclature that designated a screen and how to navigate to
it will be given in this manual in the following structure: “Icon name” [Icon Graphic] / [Tab] / [Button
Name].
For example the screen used to set the resolution of the instrument transducer would be designated by
the navigational screen hierarchy, starting from the main screen, as follows: Setup [ ] / [Sensor]
/ [Resolution]. This convention is similar to a computer folder system and will be used to describe a
screen and, inherently, how to navigate to it.
All of the screens are set up into two display areas. The larger area (left 2/3 of the screen) shows live
information about the current conguration, the progress of the test being performed and gives an indica-
tion of the output of the device. The smaller area (Data Entry) on the right side, has the number key pad,
variable sliders or discrete choice buttons (radio buttons) that all act to input alpha numeric information or
mode changes relating to the test or calibration information being shown on the left.

4.4 Transducer Removal/Replacement
When replacing transducers the order of position MUST be maintained according to
the pressure limit of each transducer; starting with the highest pressure transducer
on the left (Primary Transducer), and the next lower pressure limit transducer next
(Secondary Transducer), and the low ranged transducer at the far right (Tertiary
Transducer). If the system will be operated with less than the full complement of
three pressure modules, any empty slots must begin at the far right where the
Tertiary Transducer is normally located.
The manifold seal is a metal plate used to seal the pneumatic openings on the manifold at
an unused transducer slot. If there is just a single pressure transducer installed then two
manifold seals are installed. All transducer slots must be sealed with either transducers or
seal plates for the instrument to function. Two manifold seal plates are shipped with each
unit for this purpose.
The D-sub connectors for unused slots can remain unplugged. For more information on transducer re-
moval/replacement see Section 10.2.2 in the Maintenance section.
Up to three transducers can be present within the CPC8000. The full scale pressure of the highest
ranged transducer (the Primary transducer) must fall within the range of the installed regulator module
(see Table 4.5, Regulator Module version and range limits). This primary transducer occupies the leftmost
slot within the CPC8000 (see gure 4.4). The other two slots can be empty or occupied with lower ranged
transducers but their full scale range cannot exceed a ratio of 10:1 of the primary transducer. In other
words, the lowest full scale range in the CPC8000 cannot be less than one tenth of the range of the
primary transducer full scale range (see Section 4.6, Transducer Choices).

4.5 Regulator Ranges
The CPC8000 is supplied with one of ve dierent needle valve regulators (NVR) modules. Table 4.5
shows each regulator and its corresponding pressure range limits: LP (low pressure), MP (medium
pressure), SP (standard pressure), HP (high pressure) and EP (extended pressure).

Regulator Module Range
Figure 4.5 - Primary transducer limit for each regulator
The primary transducer (Transducer 1) full scale range must fall within one of the regulator range limits
shown in gure 4.5. The secondary and tertiary transducers may fall outside of these limits but must not
have a full scale value less than 1/10 of the primary transducer full scale range.

4.6 Transducer Choices
Transducer measuring modes can be gauge, absolute, or bi-directional. The CPC8000 will be equipped
with one, two or three transducers of the same mode. Transducer type will be “Standard” (accuracy of
0.01% FS, or 0.01% IS-50) or “Premium” (accuracy of 0.008% IS-33, or 0.008% IS-50). The transducers
must be all “Standard” transducers or all “Premium” transducers and not a mix of both types.
The three transducers, in combination with NVR Module, provide a wide dynamic range (10:1 FS) where
the operator can choose to control output pressure using a single transducer, or “autorange” control
across all three transducers. The three transducer ranges can be chosen to optimize accuracy levels.
Full scale transducer ranges up to 6000 psi are available plus an optional barometric transducer. The
accuracy specications, plus a proprietary needle valve regulator, provides accurate and stable control.
The number of unique readings/sec over the remote interface is dependent on the transducer type. The
transducer update rate of a standard transducer is 30ms, or 33 unique readings/sec. The transducer
update rate of a premium transducer is 100ms, or 10 unique readings/sec. This is a technical limitation
of the premium transducer required to meet performance specications. All remote protocols can query
faster than the transducer update rate.
An optional precision barometer can be used for emulation of gauge pressure with an absolute pressure
instrument, or used for absolute pressure emulation with a gauge pressure instrument. For full range
absolute emulation, the instrument gauge transducers should be ranged down to -15 psig.
